Science- THE CALORIE COUNTER Evolutionary anthropologist Herman Pontzer busts myths about how humans burn calories—and why
Individual Hadza had days of more and less activity, and some burned 10% more or less calories than average. But when adjusted for nonfat body mass, Hadza men and women burned the same amount of energy per day on average as men and women in the United States, as well as those in Europe, Russia, and Japan, he reported in PLOS ONE in 2012. “It’s surprising when you consider the differences in physical activity,” Schoeller says.
One person who wasn’t surprised was epidemiologist Amy Luke at Loyola University Chicago. She’d already gotten a similar result with doubly labeled water studies, showing female farmers in western Africa used the same amount of energy daily when adjusted for fat-free body mass as women in Chicago —about 2400 kilocalories for a 75-kilogram woman. Luke says her work was not well known—until Pontzer’s paper made a splash. The two have collaborated ever since.
